The summer is scorching, are your hoses fitted with sun protection?

Jun. 24, 2021

Protective cover is a collective term for spiral protective cover, hose protective cover and plastic protective cover. It is widely used in various mechanical equipment. The protective cover is like a sunscreen suit. Its main function is to protect the safety of the equipment pipelines, avoid wear Bump, improve the service life of pipelines, and ensure the safety of construction operations.

According to the needs of market development, we divide the sheath into three categories to explain, namely spiral sheath, steel wire sheath and fire protection sheath.

Today, the editor will take you to the three jacket brothers in popular science!

1. Protective Hose

   For the spiral sheath, the editor has carefully sorted out some simple and easy-to-understand identification methods, hoping to help everyone 

Observe the surface

The surface of the spiral sheath should be smooth and flat without material shortage, cracks and burrs. From a professional point of view, the better the polypropylene raw material, the smaller the molecular weight, and the more delicate and smooth the surface of the produced product.

So if you find that the surface of the spiral protective sleeve is uneven, burrs, protrusions, etc., then it is likely to be a spiral protective sleeve made of recycled rubber or polypropylene mixed with this recycled material.

Feel the hardness 

  The hardness of a good protective sleeve is generally 85-90 degrees Shore. Deviations from this range do not meet the requirements. The hardness is too low to protect and restrain the inside of the pipeline. The hardness is too high, and the protective sleeve is prone to brittle cracks in low temperature environments (such as parts of northern my country), which cannot meet the requirements of use.

Tensile Strength

The tensile yield capacity of the ordinary material spiral protective sleeve is only 25.5MPA, but the tensile yield capacity of the spiral protective sleeve produced from the original packaging material polypropylene is 28.9MPA, and the impact resistance is stronger than that of the ordinary material. Under the influence of the same external pressure, it is less prone to deformation.

2. Wire sheath

The steel wire sheath (also known as threaded sleeve, spiral sheath, steel wire threaded sleeve, threaded wire sleeve, stainless steel threaded sleeve, etc.) is a spiral coil precisely formed by a high-strength, high-precision, and smooth surface of cold-rolled diamond-shaped stainless steel wire. It is a high-precision concentric body of internal and external threads that can form standard threads. After the thread is set, it can stroke a high-precision internal thread that meets international standards. Its various properties are better than threads formed by tapping.

3.fire protection jacket

Fireproof casing, also known as high temperature resistant casing, silicon rubber glass fiber casing, is made of high-purity alkali-free glass fiber weaved into a tube, and then coated with organic silica gel on the outer wall of the tube and then vulcanized. After vulcanization, it can be used for a long time in the temperature range of -65°C-260°C and maintain its soft and elastic properties.

The synthesis of special high-temperature-resistant materials determines that the fire-resistant casing has the characteristics that many other similar materials are difficult to replace: high-temperature performance, thermal insulation performance, flame-retardant performance, electrical insulation performance, chemical stability, weathering resistance, cold resistance, and water resistance , Oil resistance, ozone resistance, voltage resistance, arc resistance, corona resistance, etc., especially safety and environmental performance. It is the best substitute for asbestos and other hazardous products.
